Business phone service / Plano, Texas
Business phone service for Plano offices that are part of something bigger.
Plano is full of regional offices, from teams near Legacy West to professional firms and clinics along the Dallas North Tollway. Many of them answer to a headquarters in another state, which means the phone system has to share extensions, queues and reporting across sites. Texwan builds hosted systems that treat every office as part of one company.
Each site gets programmed phones shipped ahead of move-in, and dialing between offices is a short extension, not a long-distance call.

01 / Threat Briefing
Threat Briefing
Voice quality across sites depends on the network, not the handset. NIST VoIP guidance recommends dedicated voice segments and traffic prioritization end to end. (NIST SP 800-58)
When an office moves, its 911 records often do not. The FCC requires a dispatchable location for 911 calls from multi-line systems. (FCC)
02 / Risk and Compliance Matrix
Risk and Compliance Matrix
| Risk | Control or compliance mapping | Business impact |
|---|---|---|
| Voice and video sharing an unprioritized link between sites | NIST SP 800-58 QoS and segmentation (NIST) | Choppy audio on calls between offices and with customers |
| 911 locations not updated after office moves or expansions | RAY BAUM’S Act dispatchable location (FCC) | Responders sent to a former suite or building |
| Each site on a different carrier and contract | Vendor management (no regulatory mapping) | Inconsistent features and renewal surprises |
03 / Architecture and Remediation Directives
Architecture and Remediation Directives
- Mark voice traffic with DSCP EF and prioritize it on every firewall and SD-WAN link between sites.
- Disable SIP ALG on firewalls and let the phone system handle NAT.
- Tie 911 location updates to your move process so a new suite gets new records before the first phone is plugged in.
- Consolidate sites onto one account so features and renewals line up.
04 / Vendor-Neutral Verification Checklist
Vendor-Neutral Verification Checklist
Three checks you can run yourself, with or without us.
- Call between two offices during the busiest hour and listen for gaps or echo.
- Check that each office’s 911 record shows its current suite number.
- List contract end dates for every phone and internet circuit across your sites.
Legacy and odd setups
Old phone systems in Plano? We can work with them.
Plano offices that have been in place for years sometimes still run a PRI into an older Avaya or Nortel system shared with a parent company. We can migrate one site at a time, keep extension numbers consistent, and bridge the old system to the new one during the transition so calls between sites keep working.
How it works
Remote setup, phones shipped ready to use
- Review. Send us your current bill or a list of numbers, users and sites. We map extensions, call flows and anything unusual.
- Build. We build the hosted system or SIP trunk configuration and program each phone (Yealink, Yeastar, Grandstream or Sangoma) with its extension and buttons.
- Ship. Phones arrive pre-configured and labeled. Your staff plugs them in; no technician visit is needed for a standard setup.
- Port and support. Numbers port on a date you approve, and support is remote, with every request answered within one business day.
Questions
Plano business phone FAQ
Can our Plano office share a phone system with offices in other states?
Yes. A hosted system can cover every site, with extension dialing between them and shared queues.
Why does call quality drop between our offices?
Usually the network: voice is not prioritized, or SIP ALG is interfering. We check both before changing anything else.
Can phones be ready before we move into a new space?
Yes. We program and ship them ahead of move-in, and port numbers on a date you choose.
